If you need to get off-Cape tomorrow [Dec. 5], you may want to skip breakfast.

To allow installation of communication lines and wires, the U.S. Army Corps of Engineers will close one of the two westbound lanes of the Sagamore Bridge from 8:30 a.m. to 5 p.m. Wednesday. Both lanes coming onto the Cape will remain open, as will all lanes of the Bourne Bridge.
